As of April 17th, 2022, the FlashKit.com website now permanently redirects to the FlashKit forum, thus breaking all original links leading to downloads for Sound FX, Sound Loops and so on.
This archive here has been put together for the good purpose of preserving the free sound loops once offered by the website. Unfortunately, not everything is accounted for (For specifics, see "missing-genres.txt". However, if there is a point where they end up fixing the site, or some kind of miracle happens, this will still stay up as an active archive of the sound loops from the site.
I've also included a few sound loop artists with their own folders of loops.
Since Flash is actively being shunned at every corner nowadays, I don't have much high hopes for the site coming back unfortunately. As it stands, FlashKit is just a community now.
